Steven Rostedt (Google) bf7e016c24 ring-buffer: Do not record in NMI if the arch does not support cmpxchg in NMI 
[ Upstream commit 712292308af2265cd9b126aedfa987f10f452a33 ]

As the ring buffer recording requires cmpxchg() to work, if the
architecture does not support cmpxchg in NMI, then do not do any recording
within an NMI.
